Polished aluminuim really does improve the appearance of nearly any classic trials
machine, and polishing is something that most people can easily carry out themselves
without any need for costly equipment, that’s certainly not worth considering for
occasional home use.

Up until the time when we obtained a large professional 3 phase polishing spindle,
the majority of polishing work carried out by Classictrial was done with nothing
more sophisticated than a 4.5 inch angle grinder, in combination with an inexpensive
No 44 polishing kit from Moleroda Finishing Systems Ltd

These kits really do work very well indeed, and with care one kit will cope with
all the polishing required on most trials machines. It’s worth remembering though
that metal polishing is an extremely dirty job, and is not something to be attempted
without considering this first.

The No 44 kit includes abrasive wheels quite able to cope with minor scratches and
slight corrosion issues, but additional coarser abrasives may be required if you
are dealing with parts in very poor condition, or want to polish roughly finished
castings to a high shine.

Our special TLR exhaust shown here was polished from the dull natural aluminuim finish
in the first picture, to the deep shine shown below, using nothing more than a 4.5
inch angle grinder, and the No 44 polishing kit that is available from Moleroda.
Moleroda also supply a wide range of metal finishing products, and are perhaps the
only UK source of professional porting equipment used in the preparation of cylinder
heads, and 2 stroke port modification work
